The dealer installed remote start kit for the 2012 Focus is unique. This information probably won't transfer over exactly to other cars but the menu access & navigation will be the same. I have only tested this on a fully loaded 2012 titanium, auto, with push-button start & MyKey. I have a uni-directional remote start, not the bi-directional.

This is combination of Option Bank settings (LED on or off) required to achieve:

-No honk at start
-No shut off when handle is touched or if the door or liftgate are opened.
-15 min run time
-2.5 sec hold on button to start

The key to the no horn/no shutoff combo is changing Bank 2 Option 1 to OFF in combination with Bank 1 Option 4 to OFF. If you leave Bank 1 Option 4 ON it will chirp 4 times at start up but not shut off on door opening. You can toggle the other options to suit your prefs. Those 4 chirps are just the system telling you that your tach needs to be programmed because you've changed Bank 2 Option 1 to Tach Mode (which it isn't) so it expects a signal between the remote start module and the engine. There is no connection in this case, hence the error chirps. I am not sure at all why this works. I'm uncertain as to why Tach Mode seems to cancel the auto shut off. If you make a mistake you can always reset the settings to default by holding the transmitter button for 3-4 seconds while in menu mode at any time. Next, change Bank 2 Option 1 to ON, and you should be at your factory installed settings.

Please post your experiences.

Sorry for a basic question....What is the difference btw the uni vs bi-directional remote start? Is it worth to pay the price difference if not yet installed or do a complete remove and replace after the dealer-installed remote start? Or what is the big advantage with the bi-directional remote start?
